Question

Superior vena Cava and inferior vena cava - Position and function​

Answer 1

Answer:

The inferior vena cava is the lower ("inferior") of the two venae cavae, the two large veins that carry deoxygenated blood from the body to the right atrium of the heart: the inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body.

After circulating through the body systemically, deoxygenated blood returns to the right atrium of the heart through either the SVC, which drains the upper body, or the inferior vena cava (IVC) that drains everything below the diaphragm.
